An In Silico Vaccine Discovery Pipeline for Eukaryotic Pathogens Based on Reverse Vaccinology - Stephen Goodswen

374

Published on

Reverse vaccinology starts with the genome of the pathogen rather than the pathogen itself. Effectively the wet laboratory in the traditional culture-based approach to cultivate, dissect, and identify antigens is replaced by bioinformatics. The laboratory validation commences with an unbiased list of all potential antigens that can be expressed by the pathogen, irrespective of life cycle stages and environmental stimuli. There are essentially four steps to reverse vaccinology: 1) predict genes within the genome of the pathogen, 2) convert gene predictions to protein sequences, 3) predict protein characteristics (i.e. potential evidence such as subcellular location, presence of secretory signal peptides and transmembrane helices) given protein sequences, and 4) collect evidence and make an informed decision as to a protein’s suitability as a vaccine candidate.
